Authorities believe 41-year-old John Orlando drove drunk early Sunday morning, stuck a pedestrian in Harrison Township and continued home to sleep it off while the victim lay unconscious in a ditch.

Fox 2 reports Orlando turned himself in Monday and has been charged with drunk driving causing death, manslaughter with a motor vehicle and failure to stop at a fatal accident. Each felony carries a maximum prison sentence of 15 years.

"He woke up apparently realizing there were some concerns and feeling some pressure that he may want to report this," Macomb County Sheriff Mark Hackel told the television station. "And then knowing the police were looking for him, he then came forward with his attorney at the sheriff's office Monday afternoon."

It's beleived that both Orlando and the victim, 38-year-old John Secord of Macomb Township, spent time at Gino's Surf Lounge on Sunday, but were not together. Authorities suspect Orlando struck Secord on his drive home at around 2 a.m.

Hackel said his office received a tip of a possible hit-and-run later Sunday morning, and paramedics arrived at the scene to find Secord still breathing shortly after 9 a.m., roughly seven hours after authorities believe the accident took place.

"He was unconscious, but apparently still alive at that time," Hackel said. "We were able to get the necessary medical personnel to the location and transport him to the Mount Clemens regional hospital. They worked on him, and apparently about an hour and a half later pronounced him deceased."

The Macomb Daily reports Orlando has a valid driver's license, but was arrested for operating a vehicle while impaired by liquor on three previous occasions, most recently in November of 2005.

Judge Sheila Miller set Orlando's bond at $350,000 cash or surety as he awaits trial.
